How about 140 years in which men are the primary caregivers of their daughters and sons, fathers get custody by default in divorce and get the house and alimony from their former wife as well, and politicians and stores cater almost exclusively to the men's vote?
Now that would be civilization changing.
And all of it would be the exact opposite of how things currently are and have been for decades.
I'm also acutely aware of the raw deal - no, the blatant and terrible injustice, something that amounts to slavery in some cases - that men are subject to in divorce and custody cases.
Dealing with the first requires a change of culture, and won't be accomplished in the sort term. Dealing with the second could be done within a year, if the will was there. It's not, partly because... it will require a change of culture.
A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.
I've not butchered a hog, only a turkey. I have no intention of dying soon, and the only invasion I've helped plan was a disaster relief effort. I've only conned a ship in simulation (which I helped write).
The kind of man I'd want as a husband and father to my children should be able to do all that - and give backrubs. And I want to be the kind of gal such a guy deserves to have as his partner.
